This is Mega Man 1 to 8 (with 9 and 10 being locked)
This is definitely better than Mega Man X Collection - (2006 game), for reasons I can't articulate. Mega Man 8 pimps the Mega Man (1994 TV series) quite hard, with a nonsense intro sequence that drags on and on.
This isn't my style of game.. I still don't understand the fact that enemies and shots can go through obstacles, and occasionally the universe will move and I'm forced to move or be pinned between the universe and the obstacles and die a horrible death.
I don't know what I'd have to do to unlock Mega Man 9 and Mega Man 10. Bribe someone, I suppose.
